Abstract
The first measurements of x‐ray‐induced electron emission for AgGaS2, a I‐III‐VI2 chalcopyrite compound, are reported. The measurements include both the valence band density of states and electronic core levels. The Ag 4d levels were found to be quite narrow and located 3.4 eV below the top of the valence band partially overlapping the heavy‐hole p‐like bands which have a maximum at 1.1 eV. The s‐like band was observed at 11.7 eV.Keywords
